Slovaks eyes: iris color, shape and epicanthic fold in 51 observed portraits
Slovaks: iris color dark brown in 35% of 51; epicanthic fold absent in 100% of 73; eye shape deep-set in 43% of 72.
Catalog portraits for Slovaks are AI-generated adult subjects; the measurements on this page come from documented photographs of real people, not from these images.
Iris color
n = 51 assessable · 26 not assessablePredominant color of the iris. Heterochromia is captured as its own value; mixed colors (e.g. hazel, blue-green) get distinct buckets.
| Value | Share | n | |
|---|---|---|---|
| dark brownIris appears nearly black under typical lighting; high melanin content. Common in East Asian, South Asian, Sub-Saharan African, and indigenous populations. | 35% | 18 | |
| brownMedium to dark brown iris; visible iris detail. | 8% | 4 | |
| hazelMixed brown and green/gold; central iris differs in color from peripheral iris (central heterochromia). | 22% | 11 | |
| blueTrue blue; highest frequency in Northern European populations, decreases southward. | 35% | 18 |
Vocabulary: Iris color (iris_color_qualitative)
Epicanthic fold
n = 73 assessable · 4 not assessablePresence and morphology of the epicanthic fold — the skin fold of the upper eyelid that may cover the medial canthus. Significant ethnic variation; high prevalence in East Asian, Central Asian, and indigenous American populations.
| Value | Share | n | |
|---|---|---|---|
| absentNo epicanthic fold; medial canthus clearly visible. | 100% | 73 |
Vocabulary: Epicanthic fold (duke_elder_epicanthus_classification)
Eye shape
n = 72 assessable · 5 not assessableOverall shape of the visible eye, considering the silhouette of the upper and lower lid margins together. Independent dimension from eyelid_crease_type and epicanthic_fold, which capture finer morphological variation.
| Value | Share | n | |
|---|---|---|---|
| deep-setEye sits deep within the orbital socket; pronounced shadow above the upper lid. Brow ridge typically prominent. | 43% | 31 | |
| almondSlightly elongated horizontal axis; mild taper at lateral and medial canthi. Considered the aesthetic reference shape. | 32% | 23 | |
| hoodedUpper lid skin descends over the lid crease, partially or fully covering the upper lid platform. Often associated with periorbital aging but can be constitutional. | 25% | 18 |

Where these numbers come from
77 publicly documented portraits of notable Slovaks people were assessed by a vision model against the catalog vocabulary, one row per portrait. Values are what the photographs show, read by a model, not population measurements. Each table counts only portraits where the value could be assessed; covered, obscured and unclear portraits are reported separately.
Notable-people corpora skew older, so hair color over-represents gray and white, and image quality varies. Treat shares as a description of this sample. Mean model confidence for this family: 0.66. 42% of portraits are high quality.
The same rows are published as image_observations in the catalog dataset; see the methodology. A family page exists only when at least 10 portraits carry an assessable value.
